Distributions of ETDs (red) and LTDs (blue) in the Gini-M₂₀ (top panels) and Gini-C (bottom panels) spaces within three stellar mass bins (left: 10.0 ≤ log(M_*/M_⊙) < 10.4, middle: 10.4 ≤ log(M_*/M_⊙) < 10.8, right: log(M_*/M_⊙)≥10.8). The red (blue) background represents the number density distribution of ETDs (LTDs) in each space. The red (blue) contours enclose 30%, 50%, and 70% of the respective subsamples. The red (blue) diamond indicates the median value of ETDs (LTDs) in each space, with ±25th percentile uncertainties. The corresponding median values and uncertainties are displayed at the bottom of each panel.
